Traxxas TRX-4 Brass Knuckle Counterweight - JR-TRX426 by Jazrider  [JR-TRX426]

Front knuckle brass counterweight for TRX-4 tuning

This JR-TRX426 counterweight is a machined brass accessory for use on Traxxas TRX-4 steering knuckles, designed to add mass at the wheel hub and alter steering inertia and overall feel.

Compatibility: designed for Traxxas TRX-4 scale and trail crawler platforms as a steering block / knuckle counterweight option. Installation attaches at the knuckle mounting points and uses the common hardware found on TRX-4 knuckles, so standard hobby tools are normally sufficient.

Tuning role: adding a brass counterweight shifts mass toward the wheel, increasing rotational inertia, which can slow steering return and improve low-speed stability and centering on technical trail sections; evaluate changes in combination with suspension and tyre choices to find the preferred handling balance.

As a scale accessory, this brass counterweight offers a clear steering feel change for TRX-4 drivers; introduce it gradually while adjusting other setup items rather than as a single cure-all.
